France’s Sanofi and Britain’s GSK said Friday their Covid-19 vaccines will not be ready until the end of 2021, after interim results showed a low immune response in older adults.
The announcement is a huge setback in efforts to fight the pandemic, which emerged in China last December and has killed over 1.5 million people worldwide.
Sanofi and GSK said the delay in their adjuvanted recombinant protein-based COVID-19 vaccine programme was to “improve immune response in older adults.”
The vaccine’s potential availability had been pushed back “from mid-2021 to Q4 2021,” they said in a statement. (Punch)
